x²-9x+8=0
x²-8x-x+8=0
x(x-8)-1(x-8)=0
(x-1)(x-8)=0
x=1, 8

Given :
x² - 9x + 8
To factorise by splitting middle term
so,
x² - 9x + 8
Multiplying coefficient of x² and constant we get 8
now,
two numbers we have to find whose sum will be (-9) and product will be 8
so
two numbers are (-1) and (-8)
check
(-1)×(-8) = 8
and
(-1) + (-8) = (-9)
so,
x² - 9x + 8
x² - 1x - 8x + 8
x(x-1) -8(x - 1) [taking x and 8 common]
(x - 8)(x - 1)
hence
two zeroes are 8 and 1
